Which of the following is an example of inductive reasoning?
- All cows eat grass;
- My cow eats grass and my neighbor’s cow eats grass; therefore, all cows probably eat grass;
- If all cows eat grass, when I examine a random sample of all the cows in Minnesota, I will find that all of them eat grass;
- Cows may or may not eat grass, depending on the type of farm where they live

and select the correct answer.
A population of 10,000 blue grasshoppers lives on an island. Most members of the population live among the grasses
because they are not very good climbers. Some grasshoppers live in the trees because they are good climbers. One year, a
short-legged mouse arrived at the island and ate all grasshoppers within its reach, thus totally wiping out the
grasshoppers living in the grasses. Luckily, those grasshoppers that were good climbers were spared. This story is an

Squirrels can be pests at bird feeders, stealing seeds away from the intended guests. The graph below shows the results of an
experiment testing a new product "Squirrel Away." On Day 1, "Squirrel-Away" was sprayed near one bird feeder. An area
around a second bird feeder in a different area was NOT sprayed with "Squirrel Away." Both bird feeders contained the same
seeds.

- I am testing the prediction that spiders with colors that match a flower (cryptic coloration) will have greater success hunting bees visiting that flower. I set up two treatments for spiders: those matching their flower and those not matching their flower. I measure how long it takes each of them to catch a bee. What kind of statistical test would be best for testing my prediction? Chi-square ●ANOVA Regressionarrow_forwarda) Does the data support your hypothesis? b) How could you improve this experiment? Consider the other factors you could have / should have controlled in this experiment.arrow_forwardA group of researchers is studying the effect of saltwater concentration on metabolism in guppies. They separate their guppies into 6 groups, each containing 3 guppies. All groups will undergo one control trial and one experimental trial. The researchers then analyzed the results. What type of t-test did they use and what is the n of this experiment? Group of answer choices paired t-test, n = 3 unpaired t-test, n = 3 paired t-test, n = 6 unpaired t-test, n = 6 paired t-test, n = 18 unpaired t-test, n = 18arrow_forward
- You are studying the diet of American bison. You gather the data in the graph below on the effort bison invest (gray bars, left hand Y-axis) in obtaining different types of grass (X-axis) and the energy content in calories of the grasses (white bars, right hand Y-axis). According to these data, which type of grass would optimal foraging theory predict bison choose?

Bright is studying whether digital or real life exhibits at the Greensboro Science Center are preferred by 8-year-old children. Specifically, she will examine whether participants spend more time at the digital animal exhibit or the real animal exhibit. In deciding how to divide children in her sample, she assigns the children who visit in the morning to the digital animal exhibit and the children who visit in the afternoon to the real animal exhibit. She records the amount of active engagement (i.e., time spent) by children at each exhibit. Dr. Bright found that children spent significantly more time in the digital animal exhibit as compared to the real exhibit and therefore concludes that 8-year-olds prefer digital exhibits. (1) Define the term “research confound.” Does Dr. Bright have any research confounds in her study (and if so, list them)? (2) Is Dr. Bright’s conclusion that 8-year-olds prefer digital exhibits valid? Explain with reference to the appropriate…arrow_forward
- Why are tropical breeds of cattle smaller than temperate breeds? Cite your References.arrow_forwardThe following statements are either true or false. Indicate true or false and justify your answer briefly. An unbiased estimator is said to be consistent if the difference between the estimator and the population parameter grows smaller as the sample size grows larger. An unbiased estimator is a sample statistic whose expected value equals the population parameter. Knowing that an estimator is unbiased neither assures us that its expected value equals the population parameter, nor does it tell us how close the estimator is to the population parameter. A specific confidence interval obtained from sample data will always correctly estimate the population parameter.arrow_forwardin response to this question, could you explain why in Step 3, R became 0.500 and why in Step 4, Vmax is sudden multiplied by 10^-3?

- How would I number it on the graph to put the averages on therearrow_forwardAfter spraying your yard with a weed-killer you notice that you don't see any bees in your yard for the next few days. You know that bees are a keystone species that is critical for a healthy environment, and want to investigate if there is a connection between the weed-killer and the absence of bees. Task: Design an experiment that could test this association by describing each of the following points with a sentence: Describe your hypothesis: Describe your dependent variable: Describe you independent variable: Describe your positive control group: Describe a negative control group:arrow_forwardWhat type of graph would you use to show how the price of gas changes over a year? bar graph histograph Opie chart line graph Question 8 (1 point) What type of graph uses a whole circle to compare the parts of a whole group? For example, how many hours in a day are spend sleeping, eating, driving, etc. bar graph line graph histograph pie chart Question 9 (1 point) Often, a large collection of data points are generated and graphed as a scatter plot and then a line can be added. What purpose does the line serve? To show the overall trend in the data to understand potential relationships between the variables. To connect all the dots so the sequence of data collection can be represented. It will enable us to remove all the random dots and just keep the line so the graph isn't so messy.arrow_forward
